Moondream is an open-source Vision Language Model (VLM) designed to be both powerful and versatile, with the ability to run on a variety of devices. It allows you to get human-like answers from any prompt.
Key Features of Moondream
- Accessibility: Moondream is designed to run on various devices, including servers, PCs, and mobile devices.
- Efficiency: It is optimized for both GPU and CPU inference.
- Capabilities: Moondream can provide human-like answers to prompts, generate detailed descriptions of scenes, detect objects, and identify X, Y locations for items in an image.
Exploring the Lineup
Moondream offers two main models:
- Moondream 2B: This model has 1.9 billion parameters and requires 2GB of memory. It supports fp16, int8, and int4 quantization and is suitable for servers, PCs, and mobile devices.
- Moondream 0.5B: A smaller, speedier model with 0.5 billion parameters, requiring 1GB of memory. It supports int8 and int4 quantization and is designed for mobile and edge devices.
Both models are trained using Quantized Aware Training and operate under the Apache 2.0 license.
How to Use Moondream
1. Installation: Use pip install moondream to install the library. Initialisation: Initialise the model with a downloaded model:
import moondream as md
from PIL import Image
model = md.vl(model="./moondream-2b-int8.mf")
image = Image.open("./image.jpg")
3. Querying: Query the image with a prompt:
result = model.query(image, "Is this a hot dog?")
print("Answer: ", result["answer"])
4. Capabilities
Moondream offers a range of capabilities:
- Query: Get human-like answers from any prompt. For example, when given an image of food, Moondream can list the items shown.
- Caption: Generate detailed descriptions of any scene. For example, it can describe a clownfish in an underwater scene.
- Object Detection: Get bounding boxes from a prompt to detect objects. For instance, it can detect drones in an image.
- Point: Get X, Y locations for specific items in an image. For example, it can identify the location of a "Sign in with Apple button".
